Although IP is based on host-machine mobility: management protocol, MlP client functionality is also applied to the network in pMip. After successfully verifying and authorizing the display at the visited network, the PM IP entity in the visited network processes the IP registration to the HA. The MN was not involved in the MIP registration process. Use a CoA from the visited network when there is a MIP and create a channel between the HA and the FA. The HA sends the datagram assigned to the MN to the CoA through the channel. The datagram is then transmitted to the MN. Since not all networks support both MIP and PMIP, when the MN moves from one network to another and the two networks do not support the same protocol (for example, wideband coded multiple access (WCDMA) supporting MIp (WCDMA) The form number AGHU * 5 I/* 31 I 098, 201004411 There is a problem when the network is connected to a wireless broadband (WiBro) network that supports PMIP. The 1A-1D diagram illustrates the handover and interaction between the WiBro network and the WCDMA network. Referring to Figure 1A', the MN establishes an initial connection to the WiBro network (step 102). The WiBro network implements PMIP, the MIP client in the MN is currently disabled, and no IP address is assigned to the MN. In order to obtain the IP address, the MN sends a Dynamic Host Configuration Protocol (DHCp) request to the WiBro network (step 104). Triggered by the DHCP request, the PMIP entity in the WiBro network initiates the HA discovery process (step 106). In order to discover the HA, the PMIP entity broadcasts a registration request with the MN identity (id) < according to RFC 3344, the HA refuses to send the subnet to the home network (subnet-d: T.rected::..) broadcast address Registration request (instead of a single issue to HA). HA discards the registration request and returns a registration reply with code 136. The registration reply includes a unicast address of 'and thus enables the PMIP entity to reissue the registration request with the unicast address. The PMIP entity receives the IP address (i.e., the home address) for the MN from the HA, and creates a binding in the HA, and the CoA registers with the home address in the HA. The home address is provided to the MN via a DHCP response (step 1-8). The MIH entity in the MN can perform MIH registration with the MIH server (step 110). At this point, the MN does not know the HA IP address and therefore has not provided the HA IP address to the MIH server. Referring to Figure 1B, the handover from the WiBro network to the WCDMA network occurs, and the MN is now connected to the WCDMA network and a new session is established (step 112). The MIP client in the MN is activated 'and the MIP client CoA is obtained from the FA in the WCDMA network (step 114). MIP in the MN is used 098111868 Form No. A0101 Page 6 of 31 0993218444-0 201004411 The UE performs HA discovery and binding update (step 116). The HA discovery must be performed each time the station client is started. See 1C® 'Occurrence'Br. Subsequent handover of the network, and the problem is now connected to the WiBr network, and the MIP client in the MN is disabled (step 118). Triggered by the MN, the pMip entity in the network performs HA discovery and binding update (step 12()). Every time (4) _ network to WiBro network handover occurs must be performed to find out, because the handling of the dragon mobility pMIp entity on the WiBr network may be connected to the WiBro network. The PMIP entity is different, and even if it is connected to the same PMIP entity after the handover, the Μ IP entity may have deleted the information of the μ N because the rib has left. Referring to Figure 1D, a subsequent handover to WCDMA occurs and is now connected to the WCDMA network (step 122). The client in the network is started, and the CoA is obtained from the FA (step 124). The client in the port is owed to the start and the binding update is found (step 126) ^When the Mlp user#

HA discovery must be performed every time a handover from the WiBro network to the WCWiA_ road occurs. In the prior art, HA discovery must be performed every time a handover from WCDMA to WiBro occurs, because the PMIP entity handling mobility on the WiBro network may be different from the pMip tone when the MN was last connected to the WiBro network. And even if the same PM ip entity is used after the handover, the MN's information booklet may have been removed because the MN has left the 'PMIP entity'. Performing HA discovery again will introduce a delay in the handover process. Also 'every time from WiBro to WCDMA, you must perform ^ discovery'. This is because when the client on the MN is started, the client 098111868 form number Α0101 page 7 / total 31 page 0983218444-0 201004411 The HA IP address was found, but when the MIP client was disabled (due to handover to WiBro), the HA's IP address was lost. Performing HA discovery again will introduce a delay in the handover process. As shown in Figure 1 A-1D, HA discovery needs to be performed on both networks each time a handover occurs. In addition to delays, problems can occur when choosing a different ha. Using a different HA will result in loss of connectivity to the corresponding node because the MN's IP address is assigned by the first HA. IEEE 802.21 Media Independent Handover (MIH) has been introduced to enable efficient software implementation between handovers between different technologies (eg, WiBro to WCDMA or vice versa) and enables both Layer 2 and Layer 3 implementations. Automatic inter-technology mobility, reduced handover interruption time, and the provision of service depletion (q〇S) between different technologies. The H A IP address can be provided to the ΓΗ server during ΗIΗ registration so that the server can perform data caching during the handover when the connection is lost. However, in the case of starting from the WiBro network, the HA IP address cannot be provided to the MIH server 'this is because the attention # is performed by the MIH client belonging to the MN' and the MN does not know the HA IP address. Therefore, the MIH server cannot perform data caching during handover until the HA IP address is discovered by the MIP client on the MN. SUMMARY OF THE INVENTION [0003] 098111868 discloses a method and apparatus for supporting handover between a first network supporting PMIP and a second network supporting MIp. After allowing wireless transmit/receive unit (WTRU) access, the pMIp entity in the first network may send a registration request to discover the HA. The PMIP entity may select the HA to respond with a predetermined code and perform a training request for the training, the predetermined code indicating the presence of a binding entry for the WTRU in the HA. 0983218444-0 Form Number Λ0101 Page δ of 31, 201004411 The PMIP entity can store the HA IP address in the authentication, authorization and statistics (acc〇unting) (AAA) feeding service Is. When the WTRU is again allowed access, the PMIP entity may retrieve the IP address from the AAA server and use the HA IP address to perform the binding update. The MIH entity in WTRu may trigger the WTRU's MIP client to perform HA discovery to obtain the HA Ip address without performing MIP registration and perform MIH registration with the MIH server to register the HA Ip address. The Mip client can retain the HA IP address when it is disabled. The MIP client can perform binding updates with the HA using the stored HA IP address. [Embodiment] [0004] The term wireless transmitting/receiving unit (subscribing ru) mentioned below includes, without limitation, a User Equipment (UE), a Mobile Node (MN), a mobile station, a fixed or mobile subscriber unit, Pager, cellular telephone, personal digital assistant (PDA), computer or any other type of user device capable of operating in a wireless environment. A method for handing over and interacting between a network that supports ΜIP (., for example, wcdma: network) and a network that supports PMIP (for example, WiBro network) is disclosed. It should be noted that WCDMA and WiBro are merely exemplary in the following description, and the embodiments disclosed herein may be applied to any type of wireless network. The 2A-2D diagram illustrates an example handover process between the ffiBr〇 network 4〇〇 and the WCDMA network 500 in accordance with an embodiment. The WiBr network 4 includes a radio access station 402, an access control router 4〇4, and an edge router 406. The PMIP entity and the DHCP entity are attributed to the ACR 404. The WiBro network 400 is connected to the backbone network 6 by the edge routers 4〇6. The hub network 600 includes a plurality of routers 6〇2 and Mcp servers, domain name system 098111868 0983218444-0 Form number A0101 page 9/31 pages 201004411 system (DNS) feeder, ΜIΗ server, ΜIP HA, attribution The AAA word server on the router 6 0 2 . The WCDM A network 500 includes a Radio Network Controller (RNC) 502, a Serving GPRS Support Node (SGSN) 504, and a Gateway GPRS Support Node (GGSN) 506 and the like. Referring to Figure 2A, the WTRU 300 establishes an initial connection to the WiBro network 400 (step 202) » The WiBro network 400 uses PMIP and the MIP client in the WTRU 300 is currently disabled' such that no ip address is assigned to the WTRU 300. In order to obtain an IP address, the WTRU 300 sends a DHCP request to the WiBro network 400 (step 204). Upon being triggered by a DHCP request, the PMIP entity in the WiBro network 400 initiates the HA discovery process (step 206). The PMIP entity sends a registration request with the WTRU ID. The HA rejects the registration request sent to the subnet-directed broadcast address of the home network instead of the ticket being sent to the HA. According to one embodiment, upon receiving a registration request, the HA first acquires a binding entry for the WTRU 300. If the HA already has a binding entry for the WTRU 300, the HA rejects with a predetermined code (eg, a code 13 edge registration request indicating that the request was rejected by the HA but there is a binding entry.

The PMIP entity receives the IP address (i.e., the home address) for the WTRU 300 and creates a binding for the WTRU in ha to cause the CoA to be registered to the home address in the HA. The home address is provided to the WTRU 300 via a DHCP response (step 208). 098111868 Table· Early bat number* A0101 Page 10 of 31 0983218444-0 201004411 After the HA discovery, the PMIP entity can save the HA Ip address in the AAA server. When subsequently handed over to the WiBro network, the PMIP entity queries the A A A feeder to authenticate and authorize W T R U 300. At the same time, the IP address of the HA is obtained from the AAA server and made available to the pMip entity. With this scheme, HA discovery does not need to be executed again by the PMIP entity, thereby reducing handover execution time. The WTRU 300 may perform HA discovery to obtain a HA IP address, and the WTRU 300 performs MIH registration with the discovered HA IP address (step 210). In order to obtain the HA IP address, an entity in the WTRU 300 may use a new interface to the MIP client in the WTRU 300 to trigger to discover that the entity is currently disabled but is still active. Thus, once triggered by the MIH entity, the MIP entity in the WTRU 300 can perform only the ha discovery without MIP registration with the HA, since the Mip registration to the .ha has been done by the PMIP entity on the WiBro network 400. For the HA discovery 'MIP client broadcast registration request. Once the registration request is received, the HA first acquires the binding entry for the WTRU 3〇〇. If the HA already has an entry for the WTRU 300, then a registration request with a predetermined code (e.g., code 137) is rejected, indicating that the request has been rejected by the HA but the binding entry still exists. The registration reply still contains the unicast ip address of the HA. If the HA does not have an entry for the WTRU, the HA rejects the request with code 136 as usual. Since the initial HA registration has been performed by the PMIP entity of the WiBro network at step 206, an HA will respond with a predetermined code (e.g., code 137) indicating that the HA has a binding entry for the WTRU 300. The WTRU 300 selects the HA. Using this scheme, the Mip client can select the same HA as the HA selected by the PMIP entity of the WiBro network. Once the HA discovery process has been completed, the MIH client in the WTRU 300 may call the MIP client to obtain the discovered ΗΑ ι ρ address, and can execute it, in the form of the WEID client 98811 leg form number A0101 page 11 / 31 page 0983218444-0 201004411. MIH registration to register the ha ip address to the MIH server. Using the provided HA IP address, the MIH server can perform data caching during the handover (when the connection is lost). In addition, once the HA IP address has been discovered, the MIp client in the WTRU 3〇〇 can remember the HA IP address even if it has been disabled. With this scheme, there is no need to re-execute when the MIP client is restarted. Referring to Figure 2B, the handover from the WiBro network 400 to the WCDMA network 500 occurs, and the WTRU 300 is now connected to the WCDMA network 5 And a new session is established (step 212). The MIP client in the WTRU 300 is established and the MIP client obtains the CoA from the FA (i.e., GGSN 506) in the WCDMA network 500 (step 214). Since the MIP client only knows the HA IP address by the HA discovery process (step 210 of Figure 2A), the MIP client in the WTRU 300 does not need to perform HA discovery again, where the HA discovery procedure is connected to the WiBro in the WTRU. It is executed when the network is running. With this approach, the delay due to subsequent HA discovery will be reduced and the possibility of selecting different HAs will be eliminated. Alternatively, the MIP client can perform HA discovery again. The Μ IP client of the WTRU 300 performs a binding update (step 216). Referring to FIG. 2C, a subsequent handover from WCDMA handover back to WiBro occurs, the WTRU connects to WiBro network 400, and the MIP client in WTRU 300 is disabled (step 218) The PMIP entity queries the AAA server for WTRU 300 Authentication and authorization, and at the same time obtain the IP address of the HA from the AAA server. Since the PMIP entity knows the HA IP address, the PMIP entity does not need to perform HA discovery again' to reduce handover execution time. 098111868 Form No. A0101 Page 12 of 31 0983218444-0 201004411 The PMIP entity performs a binding update with ha (step 220). Referring to FIG. 2D, a subsequent handover from WiBro to WCDMA occurs, the WTRU 300 is now connected to the WCDMA network 5, and the MIP client in the WTRU 300 is activated (step 222). The user is from the FA (ie, GGSN 506). C〇a is obtained (step 224). Because the client knows the HA IP address (even if it is disabled, the MIP client remembers the HA IP address) and does not have to perform HA discovery again, the MIP client performs a binding update with the HA (step 226). FIG. 3 is a block diagram of an exemplary WTRU 700. The WTRU 700 includes a transceiver 702, a MIP entity 704, and a secret 111 entity 706. The 10? entity 704 is configured to perform a MIP function including HA discovery for obtaining a HA IP address. The MIH entity 706 is configured to perform MIH functions. The MIH function includes triggering the MIP entity to perform HA discovery to obtain the HA IP address without performing MIP registration with the HA, and performing MIH registration to the MIH server to register the HA IP address. The MIP entity 704 can be configured to retain the HA IP address when disabled, and to cause the HA: IP address to perform binding updates with the HA. The MIP entity 704 can be configured to send a registration request and select an HA that responds with a predetermined code indicating that there is a binding entry for the WTRU in the HA.
